On offer here is a wonderful pair of vintage 1960's singles from the M&M Boys. The nucleus of the 1960-64 Yankees which won five consecutive A.L. flags and two World Series titles, Mantle and Maris won three league MVP's during that span. Each OAL (Cronin) baseball is inscribed and signed in blue ballpoint to fellow ballplayer. Reads, "To Al Pilarcik, My Best Wishes, Mickey Mantle" and "To Al Pilarcik, Best Wishes, Roger Maris." Both balls exhibit toning. Mantle's signature grades 7/10 while Roger's autograph comes in at a 5/10. Each certified by PSA. Obtained from estate sale of the former major leaguer.
